Study on the Usability of Different Combine Machines in Wheat and Rice Fields

Many attempts were carried out by many projects and achademic institutes to investigate the proper method of wheat and rice production in respect to decrease grain losses, and cost of production. As it is known that the small holding represents about 70% of total planted area in Egypt. The mechanization of wheat and rice in this type of areas is still a problem facing the producers. The objectives of this work is : 1- to select the proper equipment used in wheat and rice harvesting in small holdings under different forward speeds. 2- effect of field length on field efficiency. 3- Select the Daily time during the proper period to harvest wheat and rice under different condition of equipment and field.
